A Promise to a Free and Open Indo-Pacific
A renewed promise to keep the Indo-Pacific region free and open is at the heart of the talks. Japanese officials think this framework is important for keeping the region stable and following international law.
Britain has been more and more in favor of getting involved in the Indo-Pacific, which shows that it has a role to play outside of Europe. The conversation focuses on security at sea, a rules-based order, and the right to move freely.
China’s Growing Military Influence Shapes Talks
The growing military presence of China is still affecting how Japan and Britain plan for their own security. Officials think that deterrence and cooperation in different regions are becoming more connected across continents.
Allies have had to work together more because they are worried about power imbalances. Tokyo and London both think that security in the Indo-Pacific is linked to stability in the Euro-Atlantic.

Defense Cooperation Expands Through Joint Programs
Through exercises, sharing intelligence, and working on projects together, Japan and Britain have steadily strengthened their defense cooperation. These projects show that trust and operational alignment are growing.
One of the most important projects is a 3-way program with Italy to make a new fighter jet. The goal of the project is to be in use by 2035, which will improve the air power of allies.
Economic Security Becomes More Important Strategically
Economic security has become a key part of the relationship between the 2 countries, in addition to defense. People are now talking a lot about protecting technology and making supply chains more resilient.
Japan and Britain, 2 of the world’s biggest economies, want to make important industries less vulnerable. After Brexit, London has been working more closely with partners in the Indo-Pacific.
Trade Ties Strengthened Through Regional Agreements
Britain joining the CPTPP in 2024 was a big step forward in working together with Japan on economic issues. The trade agreement strengthens both sides’ promises to keep markets open and set high standards.
Japan has backed Britain’s entry into regional trade groups. The deal makes trade between the 2 countries stronger while making them less reliant on exposure to a single market.
Diplomatic Continuity Amid Broader Global Engagements
Starmer’s trip to Tokyo comes after his recent high-profile trip to China, which shows how Britain uses multiple tracks in diplomacy. Finding the right balance between engagement and competition is still a major foreign policy problem.
The meeting shows that Japan and Britain’s relationship is still strong, even though things are changing in the world. Leaders want to show that things are stable, people are working together, and they have a clear plan for the future.
